If you or anyone you know has experienced any of the early symptoms of a low blood sugar reaction, you need to treat it as soon as possible. The first thing you want to do is eat or drink something that has sugar in it. Try a hard candy, sugar-sweetened soda, milk, or orange juice.
Excessive Saliva is not a condition in itself, although it is particularly known among doctors and is called in technical terms as sialorrhea, though it is more commonly referred to as drooling.n some cases, though the condition itself does not lead to excess saliva, the medication a person takes for the condition can lead to this problem. This is commonly a side effect of medication used to treat schizophrenia.
Expert: Dr. D. Evans replied 7 years ago. Saliva being foamy means that not enough water is present in the saliva. Saliva contains mucoproteins and glycoproteins, when there is not enough water, this can cause foaminess. The most likely cause is simply that you are dehydrated and not taking enough water.
